1. Conditions of safe operation

1.1 Warnings

• After connecting converter to the supply network, internal circuit components (except In/Out clamps) are on the supply network potential. Touching them can cause an electric shock..

• When you connect the converter to the supply network there is a dangerous voltage on clamps U, V, W, even when the motor does not work.

• After disconnecting the device from the supply network the dangerous voltage is still present for about 5 minutes.

1.2 Basic rules

Don’t make any connections when the converter MFC71 0/AcR is connected to the mains. Don’t connect mains voltage to output clamps U, V, W . Don’t measure the voltage endurance of any unit dev ices. To measure the cables insulation it is necessary to disconnect them from the converter. Don’t touch integrated circuits and any other parts on the converter's electronic board, as they can b e

damaged by electrostatic discharge. Don't connect any capacitors to motor wires intende d for improvement of power factor Don't measure output voltage of converter using dig ital voltmeters

1.3 Operation listThe operations applied at installation and the firs t start-up of the electric drive

After unpacking the converter, it is necessary to check up visually presence of damages which could arise during transport.

Check up the correspondence between the delivered frequency converter and the order - check up the ratings plate on the case. Delivery includes:• the frequency converter with the User's manual,

• a choke or L-C-L filter – if it was ordered

• a ferrite ring or RFI filter - depending on the order.

Check up the correspondence between conditions in which the converter will be used and conditions of an environment for which it is designed (section 1.4).

Installation of the frequency converter should be made according to principles of safety and EMC rules, listed in section 2.

Choose a configuration of the frequency converter and realize it according to sections 4 and 5.

1.4 Environmental conditions

Degree of pollutionDuring design second degree of pollution has been assumed, at which there are normally only non-conducting

pollution. However there is a probability of temporary conductivity caused by a condensation, when the converter doesn't work.In case the environment in which the frequency converter will work, contains pollution which can influence its safety, it is necessary to apply appropriate counteraction, using, for example, additional cases, air channels, filters etc.

2. Installation of the frequency converter

2.1 Connection of a power circuits

The MFC710/AcR was derived from MFC710 base unit by including a regenerative (active) AcR rectifier. It allows to eliminate problems with mains current and voltage harmonics and correction of PFC Power Factor, reduction of THDi (Total Harmonics Distortion) and THDu is possible.

MFC710/AcR draw a sinusoidal mains current and eliminates negative impact on mains voltage in case of using standard rectifier.

Base features of MFC710/AcR:• Two-way power flow, four-quadrant work,• Voltage stabilization in DC-link

MFC710/AcR is feeded by standard 3x400V AC mains. Optionally can be connected to 3-phase mains 2x230 – 3x690V. It should be known, that all parameters results from load current are calculated for 3x400V standard mains.On fig. 2.1 mains and load connections are shown. Wire diameters and mains-choke type should be selected on load current. Required current breakers and wire diameters shown on Tab. 0.2 and 2.1 and should be selected depending on current of a load. Appopriate protection values are listed in table 0.2 and recommended values of wires cross-section are listed in table 2.1. Additional information about external connections can be found in section 2.1.1 under the “Equipotential connections” and in section 2.1.2. In order to comply with EU directives of electromagnetic compability (EMC) application of a four-wire shielded cable (three phases + earth wire) is recommended to fed the engine. The frequency converter is supplied with appropriate resources, protected from corrosion, dedicated to make apropriate connections. Type of mains choke and protections is available at producer's representative. It is strogly recommended not to use any switches or contactors at the converter output that could disconnect system during the run.

The MFC710/AcR converter is fed from the three-phase 3x400V mains. In the fig. 2.1 the scheme of power circuits connections is presented.

Overcurrentprotection(gR or aR)

2.1.1 Safety rules

Equipotential connectionsThe protection against indirect touching live parts consists of automatic switching off by special short-circuit

protection (or differential-current protection) or voltage limitation to a level not exceeding acceptable values, in case of an insulation failure.

The short circuit to ground at the frequency converter output can be not detected by short-circuit protection, devices due to DC link circuit. The protection against interpolar and ground short-circuit on the output of the converter is provided. However this protection is based on IGBT transistors blocking, what does not conform to the requirements of fire-prevention protection. Due to that, for safety of staff, it is necessary to make local equipotential connections.

In the frequency converter there are provided appropriate terminals, properly marked, protected from corrosion to make equipotential connections.

ProtectionThe minimum values of input wire short-circuit protection are presented in the table 0.2. Usage of gG or aM

fuses is allowed in the circuits, however taking into account necessity of protection of the rectifier bridge of the frequency converter, the best solution is gR or aR fuses. You can use overcurrent protection, but the response time of such devices is longer than properly chosen fuse.

Frequency converter is protected from: drive overloading, motor overheating, under- and overvoltage in an DC link circuit of the converter, a short-circuit at the converter output (it protects converter only!!).

Usage of differential-current protection due to electrical shock prevention can appear unfavorable, since it can trigger due to temporary or constant leakage current of the power drive system, working in normal conditions. In case of usage of the differential-current protection devices you may use only cut-out switches of a B type, due to different nature of a differential current.

Disconnecting deviceIn order to comply with EU directives, according to PN-EN 60204-1:2001, power drive, which consists of a

frequency converter and electrical machine should be supplied with a device for disconnecting power supply. This device should be one of listed below:• separator (with or without fuses), category of usage AC-23B fulfilling the requirements EN 60947-3,• disconnector (with fuses or without), disconnecting a load circuit before opening main contacts, conforming the EN

60947-3 requirements,• tripper conforming the EN 60947-2 requirements.User is obliged to fulfil this requirement.

Emergency stopIn order to comply with EU directives and PN-EN 60204-1:2001 and for personnel safety and equipment, it is

necessary to use an emergency stop switch, which has higher priority than other functions, irrespective of operating mode. The key STOP on operator panel cannot be treated as the switch of abnormal break, because it doesn't disconnect a frequency converter from power supply. User is obliged to fulfill this requirement.

CasingThe casing conforms to the requirements of a IP20 protection degree. The surface, on which the control panel

is situated fulfills the requirements of a IP40 protection degree. The casing was designed in such a manner that it cannot be removed without usage of tools.

C apacitors discharging In a DC link circuit of a frequency converter there is a capacitor battery with relatively high capacity. After

turning off of a supply voltage in its clamps dangerous voltage is present for a certain time. It is necessary to wait for 5 minutes before making connections on clamps of power terminal strip of a frequency converter. The information about danger of such voltage is placed also on terminal strip cover.

2.1.2 Electromagnetic compatibility (EMC) rules

The installation principles reducing EMC problems are divided into four groups. To achieve full success it is necessary to apply all principles listed below. Not applying to one of principles ruins the effect of others.

• separation,• equalizer connections,• shielding,• filtration.

The basic way of connecting the filter, the frequency converter and the motor is presented in the figure below

SeparationPower cables (supplying, motor's) must be separated from signal wires. It is necessary to avoid parallel leading

of power and signal wires in the common wire channels, and especially in group of cables. The crossing of power cables and signal cables under a right angle is allowed.

Equipotential connections The frequency converter and the filter should be mounted as close as possible, preferably on a common metal

plate which act as a ground. For this purpose you can use, a mounting plate or a back wall of a case for example. The

casing of the frequency converter, the filter and the metal plate shouldn't be coated with any insulation materials. It is necessary to pay attention to an opportunity of oxidation of a surface that results in deterioration of contact. For restriction of asymmetric disturbance level, it is necessary to apply many connections of the cable shielding to ground.Additional information about equipotential connection can be found in section 2.1.1.

ShieldingWires between the mains filter and the frequency converter are not necessary for shielding, if their length

doesn't exceed 300mm. In case the length of conductors exceeds 300mm it is necessary to use the shielded wires. Completely shielded cable is a cable which fully complies with requirements of interference radiation according to EN 55011 norms. Such cable should have the screen consisting of spiral metallized aluminium foil and tinned copper plait with a puls-duty factor of not less than 85 %, not separated galvanically.

Connection of the cable ends to ground is obligatory. It is necessary to use grounding of the cable shielding on whole section of a cable, on both ends. For this purpose a special EMC grommets are used. They provide valid contact of cable shielding to the case of the equipment. In addition it is necessary to use special cable clips to connect it to back wall of a case for example. It is necessary to pay attention that the unshielded cables, are as short as possible. Junctions of the shielding with a ground should be free from insulating coat on a whole section. Be careful not to damage the shielding. It is not recommended to weave the copper plait in one point (without using EMC grommet) in order to realize grounding.

In case of need control signal wires should also be shielded using the same principles.

F iltration Use of the EMC filter limits noises spreading from electric drive system to mains. Principles of filter installation

are described at the description of equipotential connections and shielding.

Ferrite ringsFulfilling the requirements, concerning interference emission in the first environment

and limited distribution, can be realized by using of ferrite rings instead of additional RFI filter (in converters with rated power 15kW and below). It is necessary to remember the warning placed in section 15, page 60.

The ferrite ring which is delivered together with the frequency converter should be placed on a supply cable of the frequency converter, as on the figure 2.4.

The list of the equipment reducing EMC problemsThe list contains the equipment which can be additionally established in the

3. The control panel

Control panel serves for constant review of the process parameters (rotational speed, current), the operating mode control (START / STOP, change of the referencing unit, cancelling fault message) and also for viewing and changing of converter's parameters. In the panel LCD display (2x16 symbols) is used. It has function of contrast regulation. On a client's wish, instead of LCD display, 6-digit LED display can be installed, which has advantage in case of necessity of good visibility at a great distance.

After switching on the converter to mains, the control panel is switched on in the Base Mode in which both lines of the display are occupied with parameters as it is shown on fig. 3.2.

There is a possibility of programming values presented on the display. – see section 3.3.

On fig. 3.3 the main sequence of control panel service is presented. Viewing and option of parameters in groups 0...6 are shown on fig. 3.7 (section 3.1).

CHANGING REFERENCING-UNIT with the help of keys of arrows up / down allows to adjust speed of rotation of the motor from the control panel. It is possible when the control panel is in a base mode or in a mode of fast review and at least one of the following conditions is carried out:

current control (A or B) is switched on setting operation frequency from the control panel (par. 2.2 for control A and 2.3 for control B),

referencing-unit of PID- regulator is set for control from the control panel (par. 2.60),,

one of four user referencing-unit (see section 10.5) is active.

At the same time only one of these referencing-units can be used or they aren't used at all. If referencing frequency from the control panel is switched on, screen display, after pressing one of keys , will look as it is shown on fig. 3.4.

THE CONTROL STATE allows to receive the information about which referencing-unit of drive frequency and source of a START/STOP signal are used in the circuit. To enable the CONTROL STATE on the display it is necessary to press a

key. The effect will be such as it is shown on fig. 3.5..

3.1 Viewing and changing parameters valueFrom a BASE MODE into the PARAMETERS MODE we

pass by pressing a key of a double arrow . The next pressing of this key results in change of parameters group, starting from group 0 up to group 6. After group 6 the panel comes back into the BASE MODE (see fig. 3.3).

In the PARAMETERS MODE there is an opportunity of viewing and changing the converter's actual parameters. On fig. 3.6 an example of displaying parameter 1.20 is shown.

Keys up / down help to choose number of parameter from the current group of parameters. Change of parameters group is achieved by pressing the key of a double arrow . Pressing key of asterisk will result in transition to the PARAMETERS SETTING MODE (only in a case if setting of parameters is not blocked). In a mode of parameters setting value on the display is surrounded by square brackets (as shown at Fig. 3.7).

3.2 Blocking parameters and access controlIf the parameter on display looks like at the

fig. 3.8 (“[b]” at the beginning of bottom line), it means that it is blocked (changing is impossible).The possible reasons of blocking of parameter changing: Some parameters can be changed only if the

system of the electric drive does not operate (the drive is stopped),

Blocking of parameters changing is switched on - see section 3.2.1, Changing of parameters is blocked by a code - it is necessary to enter a corresponding code of access - (see

section 3.2.2 and the next).

Table 3.2 - Parameters which are responsible for blocking and access control.

Parameter Value

4.1 Usual blocking of parameters, set up to «YES» when the frequency converter is turned on. If there is no code access in the system, changing to «NO» allows to change parameters.

4.2 Current access level (reading), entering of access code (record).

4.3 Change of access code for current access level.

4.4 Restoring to factory options of the frequency converter.

4.5 Blocking of parameters record in EEPROM (don't use - service parameter).

3.2.1 Unblocking changing of parameters

When supply of the frequency converter is switched on, the parameter 4.1 (blocking of parameters) is established to YES, what makes any changes in options of system impossible. Change of the given parameter to NO (fig. 3.9) allows changing parameters. ATTENTION: If access to parameters is blocked by a code (see section 3.2.2 and the next) in this case it is impossible to unblock access to parameters without entering a valid code. (Changing of parameter 4.1 in this case will be unsuccessful).

3.2.2 Blocking by an access code

With the purpose of protection of the frequency converter options from possible intervention of unauthorized persons system of access codes is used . The access code can be a number from 0 up to 9999. Entering the access code enables changing of parameters of the converter and is carried out with the help of parameter 4.2 (fig. 3.10). There are two unblocking codes:

• CODE1 - causes blocking of most of converter's parameters. Value 0 means, that CODE PROTECTION IS SWITCHED OFF, any other value activates blocking.

• CODE2 – its entering is necessary for loading factory options of the frequency converter.

According to access codes three levels of parameters' access are possible:

• level 0 (lowest) – SYSTEM IS PROTECTD BY AN ACCESS CODE. At this level it is impossible to change parameters of the frequency converter. The parameter 4.1 (parameters blocking) at this level in all cases has value YES and it cannot be changed.

• level 1 - is switched on after entering of correct value CODE1. At this level it is possible to change the majority of parameters of the converter.

• level 2 (highest) - Enables loading one of the certain variants of factory option. In order to switch on this level of access it is necessary to enter CODE2. At this level it is also possible to change all parameters of the converter.

Current level of access can be determined by reading parameter 4.2. (see fig. 3.10a).

3.2.3 Unblocking changing of parameters of the electric d rive, blocked by a code

If access to changing the parameters is blocked by a code in this case unblocking procedure shown on fig. 3.10 (OBLIGATORY CONDITION IS THE KNOWLEDGE OF THE ACCESS CODE).

Entering appropriate access code (CODE1 or CODE2) results in automatic change of parameter 4.1 (Parameters blocking) to NO.

Blocking with access code is turned on when the value of CODE1 differs from 0. The procedure of setting new CODE1 is shown in a fig.3.11 with the reservation that CODE1 value must be different from 0. From this moment on the parameters of the system of the electric drive will be protected from changes by persons that do not know the access code.

3.2.5 Disactivating protection by access code

It is necessary to enter current CODE1 as shown on fig. 3.10. Then set CODE1 to 0 (fig. 3.11).

3.2.6 Change of access codes

The change of the access codes to level 1 (CODE 1) and level 2 (CODE2) takes place as it is shown in a fig. 3.11. To change CODE1, the converter should operate at Level 1, and to change CODE 2 the converter should operate at Level 2. At Level 0 access codes are absent.

3.2.7 Loading of factory options of the converter

To load factory parameters, it is necessary to enter CODE2 (fig. 3.12a). The electric drive will pass to Level 2 (fig. 3.12b), in this case it is possible to select variant of factory options for loading (fig. 3.12c). 9 different variants of factory options (ready programs) are provided, which can be selected by the User as base (see section 7).

3.2.8 Factory values of access codes

• CODE 1 (change of parameters) = 0• CODE 2 (loading of factory options) = 1

3.2.9 Full pointers

Setting a parameter which is a pointer from outside of available range (e.g. setting par. 2.2 as “256 > BL1”) is allowed when function of full pointers is turned on (par.4.6 on YES).

3.3 Change of displayed values

The values presented on both lines (top and bottom) of display in the base mode and in the mode of fast reviewing are selected from group 0 of parameters. There is a possibility of changing factory options and a possibility of choosing to each of these lines any parameter from this group. Table 3.3 presents list of parameters determining what values are displayed.It is possible to program other then original sequence of parameters displayed in bottom line of the panel in fast review mode. Each of sequence positions SP (SP1 ... SP7) has a parameter that assigns value from group 0 to appropriate sequence position.

3.4 Contrast regulation

Control panel of the converter MFC710/AcR is supplied with a regulator of contrast. This function has the relevant value when temperature in operating environment varies in a wide range. The visibility is regulated by adjustment of the parameter 4.21 (fig. 3.14).

If the visibility is established in such a manner that display images it is not visible, there is a possibility of a “fast” entering into the mode of adjusting of the parameter 4.21 according to the procedure below:

switch off the frequency converter and wait while control panel “will go out” switch on the frequency converter holding one of keys the converter will switch on in the mode of setting the parameter 4.21 (fig. 3.14). change visibility with keys , set the optimal value confirm adjustment of the visibility value with the key Błąd: Nie znaleziono źródła odwołania .

4. Configuration of the frequency converter

4.1 Setting nominal parameters of the motorBefore the first run of the frequency converter it is necessary to determine nominal parameters of a motor.

Appropriate data can be received rating plate. It is necessary to enter the following parameters:• Parameter 1.1 - rated power of a drive of [kW], • Parameter 1.2 - rated speed of a drive (rpm)• Parameter 1.3 - rated current of a drive [A] • Parameter 1.4 - rated voltage of a drive [V]• Parameter 1.5 - nominal frequency of a drive of [Hz] • Parameter 1.6 - nominal cosφ of a drive

Check Appendix C for more details.In the mode of scalar U/f control these data it is enough for converter operation.

4.1.1 Preparation for operation in a vector control mode

In case converter operates in the mode of vectorial mode (with the sensor or without it), additional definition of parameters of a so-called “equivalent circuit of a motor” (fig. 4.1) is necessary.

Parameter 1.11 - pure resistance of stator windings Rs [Ohm]

Parameter 1.12 - pure resistance of rotor windings Rr [Ohm] (the parameter 1.12 is defined automatically by converter MFC710/AcR on basis of other drive parameters - it is impossible tochange)

Parameter 1.13 – main inductance Lm [mHz]

Parameter 1.14 - inductance of a stator Ls + Lm [mHz]

Parameter 1.15 - inductance of a rotor Lr + Lm [mHz]

Parameter 1.16 – additional inductance - connecting wires, choke

Without definition of the value of these parameters operation of the converter in the mode of vectorial control is not possible. Setting of incorrect values of these parameters results in bad system operation. The parameters correspond to a motor in star connection (Us – phase voltage).If we cannot define these parameters then the built-in function of IDENTIFICATION RUN described in section 5.1 will help us.The parameter 1.20 OPERATING MODE must be set on value:

Vector1 – mode without the sensor - there is no necessity of encoder but thus the accuracy is lower, Vector2 – operating method with the sensor of a position (encoder). The encoder resolution is defined with the

help of the parameter 1.80. This mode is recommended for operation on low frequencies of rotation (lower than 2.0 Hz)

.4.2 Control

Main possibilities of converter control – referencing output frequency (rotation rate) and configuration of control with a START / STOP signal - are described below with additional information about configuration of output relays of a converter. More detailed information is in „parameter list” - Appendix C. The control possibilities of the converter arise from the analysis of a structure of the control system - fig. 4.2b/4.2c.

4.2.1 Structure of control

In control system of the converter MFC710/AcR there is a philosophy of 2 independent „control places” A and B, that allows to change whole structure of the converter control (sources of START and STOP signals and sources of frequency for electric drive operation) by changing only one parameter. In fig. 4.2a there is simple diagram and in fig. 4.2b and 4.2c there are developed diagrams of the converter control.

4.2.2 Control from the control panel

In order to control the electric drive from the control panel it is necessary to:

choose „ control place ” A or B with the help of parameter 2.1 establish parameter 2.2 (for A) or 2.3 (for B) to in position „> 133 Keys ” establish parameter 2.4 (for A) or 2.5 (for B) to in position „> 31 Keys ” make sure, that the constant speed mode isn't chosen: Par. 2.30, 2.31 and 2.32 should be established in

position „> 0 Switch off ”

The picture on the display „ control state ” will be as it is shown on fig. 4.1 – referencing-unit and local START STOP from the control Panel. At this configuration change of frequency value of the electric drive (or speeds of rotation in a mode of vector control) is carried out by keys . Start and a stop of the drive is carried out also from the Panel with keys LIFT/RIGHT and also STOP.

4.2.3 Control through terminal connections

To have an opportunity of control of the electric drive through terminal connections (e.g. START / STOP through digital inputs and regulation of rotation s peed with the help of a potentiometer ) it is necessary:

To choose „ control place ” A or B with the help of parameter 2.1 To set up value of parameter 2.2 (for A) or 2.3 (for B) in position:

– „> 134 AI0 ” for an analog input 0– ,,> 135 AI1 ” for an analog input 1– „> 136 AI2 ” for an analog input 2

To set up value of parameter 2.4 (for A) or 2.5 (for B) in position „> 30 Input Digital ” To be sure that the choice of a mode of constant speed is not made: values of parameters 2.30, 2.31 i 2.32

should be set up „> 0 Switch off” To set up parameter 2.8" Remote start ”. It defines functions of control digital inputs as at the tab. 4.1

Table 4.1 - possible configuration variants of remote start (START)

Value of par. 2.8 „Remote start”

Notation Function

0 DI1 = START/STOP DI2 = DIRECTION

Voltage feeding to digital input 1 results in start and voltage removal - stopping of the electric drive. The condition of a digital input 2 defines change of a direction of drive rotation

DI1 = START to the RIGHT

DI2 = START to the LIFT

Voltage feeding to digital input 1 results in a drive start. Voltage feeding to digital input 2 results to a drive start in opposite direction.

4.2.4 Work with constant speeds

The system can work with one of seven constant speeds. The choice of constant speed is made by digital inputs determined by parameters 2.30, 2.31 and 2.32 - an example in table 4.2. Sizes of constant speeds are defined by parameters:

par. 2.33 – constant speed number 1 [Hz]par. 2.34 – constant speed number 2 [Hz]par. 2.35 – constant speed number 3 [Hz]par. 2.36 – constant speed number 4 [Hz]par. 2.37 – constant speed number 5 [Hz]par. 2.38 – constant speed number 6 [Hz]par. 2.39 – constant speed number 7 [Hz]

2.32 W3 >0 SWITCH OFF.

W3 = 0

!!! ATTENTION!!! - see structural circuit of frequency referencing-unit - section 4.2.1

As a result of choice of such parameter configuration it is possible to choice between 3 available constants through digital inputs 3 and 4:

State DI3

State DI4

CONTROL STATE display when constant speed referencing-unit is active looks like it is shown on fig. 4.5 – Referencing-unit: constant frequency (speed), START through digital input.

4.2.5 A motopotentiometer

Motopotentiometer is a simple “increase-reduce” device for speed control of drive rotation with help of two buttons. An example way of connecting “increase-reduce” buttons to the frequency converter is shown on fig. 4.6a. Fig. 4.6b. Illustrates action of the device In order to set the output frequency of the converter with help of a motor-potentiometer par. 2.2 (for control A) or 2.3 (for control B) must be set on value "MotPot" (mP).

21

Fig.4.5.- CONTROL STATE

A nMot 0 rpmA nMot 0 rpmA nMot 0 rpmA nMot 0 rpm Ref:Fc Cont:DiRef:Fc Cont:DiRef:Fc Cont:DiRef:Fc Cont:Di

Attention: Fig. 4.6a corresponds to a situation when par. 2.20 = “DI3” and par. 2.21 = “DI4”.

There are four available modes of motopotentiometer operation: 0, 1, 2 and 3. Modes 0, 1 and 2 should be used only when current referencing-unit (par 2.2/par. 2.3) is set on “MotPot”. Mode 3 can be used regardless of setting of current referencing-unit.

Stopping the converter In mode 0 will cause reset of motopotentiometer settings. In mode 1 settings of motopotentiometer will be stored and there is no possibility of changing it while the drive is stopped. In mode 2 settings of current referencing-unit

are traced by motopotentiometer so switching from current referencing-unit to motopotentiometer's referencing is made very easily. In mode 3 configuration of motopotentiometer is stored and there is possibility of changing it while the drive is stopped.

4.2.6 Other possibilities of the frequency converte r control

Other possibilities arise from the analysis of the block diagram of control (see section 4.2.1). From the major options it is possible to allocate

Change of control place A / B e.g. with the help of a digital input - par. 2.1 Mixed control – e.g. Referencing frequency from the control panel and a START / STOP signal from digital

inputs, Control through RS232/RS485 connection (see section 13), Referencing frequency from an output of the PID-regulator (see section 8), Advanced functionalities connected with using of built-in control system PLC or a control system of group of

pumps (see section 10 and farther).

4.2.7 Configuration of digital and analog inputs an d outputs

Digital inputsFrequency converter has 6 digital inputs designated DI1... DI6. Submission of 24V voltage on any digital input

(terminal strip – fig. 2.6) sets it in a logic state 1. Current state of digital inputs can be read with the help of parameter 0.48 (fig. 4.7a - "110000" means that voltage 24 V is sent on DI1 and DI2).

Digital inputs have no parameters which define their function. Such function is determined only for “remote start” (see table 4.1) and also “thermal blocking” for DI6 - see section 4.4.3.2. In other cases the digital input "is selected" for using the certain functions with the help of parameters which are connected to the given function of the frequency converter, e.g. to choose control variant A or B using DI3 it is necessary to set up par. 2.1 (which makes choice of control variant) on value In,C3 as it is shown on fig. 4.8. It means that there is a possibility of giving to this digital input simultaneously more than one function. (Other parameter can be set up also on value “In,C3”).

Analog inputs,Frequency converter has three analog inputs (In,А0, In,А1 and In,А2). Two of them (In,A1 and In,A2) can

operate both in voltage mode 0 (2)... 10V and in current mode 0 (4)... 20mA. The choice of an operating mode for these inputs is carried out with the help of switches J3 i J4. InputА0 can work only in voltage mode. It is possible to connect directly a potentiometer or a voltage (current) source to analog inputs - see fig. 2.7. Table 4.3 compares the parameters responsible for a configuration of the analog inputs. By analogy to digital inputs, analog inputs have no parameters which define their function in the system. Inputs are selected by control configuration parameters to perform certain actions. (fig. 4.9).

3.23 Reaction to signal absence at the Analog Input

In structure of the electric drive Analog Referencing-units are also provided. Analog referencing-units are strictly connected to Analog Inputs, from which they differ, that they have parameters carrying the information on value of their offset and scale. Usually analog referencing-units are used only as inputs for the PID-regulator, however they can be used as inputs for PLC controller or after expansion of parameters range(see section 11.3) as control signals in any point of the structural diagram of control (e.g. fig. 4.9b). In the table 4.4 there are parameters which define a configuration of Analog Referencing-units and dependence of value Ref.A from AI.

Digital outputs (relays)In the converter there are 4 digital outputs:

3 relay outputs 250V ~ / 3A which are called K1, K2 i K3 (or DO1, DO2 and DO3) 1 „open collector” output 35V / 250mA marked DO4

Each digital output can simultaneously realize up to two programmed functions. In table 4.4 there are parameters which serve for a choice of functions of digital outputs.

By changing parameters from table 4.4 it is possible to choose advanced functions, which allows to control relay outputs with the help of built-in control system PLC. In Pumps control variant configuration of digital outputs are responsible for control of contactor group which enable separate pumps.

Analog outputsTable 4.5 presents parameters which concern configuration of two analog outputs AO1 and AO2. Both outputs

can operate in a voltage mode 0-10V (2-10v) or in a current mode 0-20mA (4-20mA). The choice of an operating mode is carried out with the help of switches J1 for OutА2 and J2 for OutА1 (see fig. 2.6).Analog outputs in voltage mode should be loaded by impedance in value not less then 10kOm.

4.3 Configuration of the electric drive

4.3.1 Establishing dynamic characteristics and ways of hal ting the electric drive

Dynamics decides about changing rate of the drive rotation speed - start and halting, reverse speed. In MFC710/AcR converter you can choose dynamics from two accessible variants which are named DYNAMICS1 and DYNAMICS2.

Parameter 1.30 - Acceleration 1 - time of acceleration from 0Hz to 50Hz (Dynamics 1)

Parameter 1.31 - Delay 1 - time of delay from 50Hz to 0Hz (Dynamics 1)

Parameter 1.32 - Acceleration 2 - time of acceleration from 0Hz to 50Hz (Dynamics 2)

Parameter 1.33 - Delay 2 - time of delay from 50Hz to 0 Hz (Dynamics 2)

Parameter 1.34 – S Curve - allows to realize the smooth beginning and end of acceleration and Delay

Parameter 1.36 - Choice of DYNAMICS - allows to set up dynamics variant 1 or 2. You can also decide, that the choice of dynamics will be carried out through one of digital inputs.

ATTENTION: setting up too small time of acceleration can result in occurrence of „high current” failures during the start-up, especially at significant loading of the drive.

4.3.2 Formation of U/f characteristic

In modes of scalar control U/f there is an possibility of influence on type of the characteristic. In modes of vector control (Vector 1 and Vector 2) parameters of U/f cha racteristic formation are not relevant.

The main parameter which influences on form of the electric drive characteristic is par. 1.20 "Operating mode”:

Mode U/f linear. It is used if there exists a constant moment of loading which does not depend on speed (see fig. 4.11).

Mode U/f square-law. It is used if the moment of loading grows under the square-law from speed (e.g. the electric drive of the fan). Use of square-law characteristic U/f cause reduction of noise and decrease of losses in the motor (see fig. 4.11).

4.3.3 Elimination of frequencies

Parameters 1.66 and 1.67 allow to define voltage (in % Un of the motor) and also time (in seconds) of braking the drive by a direct current. In case time of braking is set up on 0 sec this function is switched off.

4.3.5 Mechanical brake

!!! CAUTION !!! In case when generation of full torque is required at zero speed of a drive, it is recommended to use vectorial mode of control – par. 1.20 “Vector 2” and to apply encoder.

MFC710/AcR allows to cooperate with mechanical brake of a power transmission system. An example of connecting the brake is shown in fig. 4.13. Braking control is made by appropriate configuration of relay input (appropriate parameter 2.90 ... 2.96 set on “Brake”(Br.)). Functioning of mechanical brake control is shown in fig. 4.14. In table 4.6 configuration parameters are compared.

2.102 Br. close n Below this speed a command to close the mechanical brake is sent. [rpm]

2.103 Br. close t. Time of work after closing command is sent [s] – time needed for complete locking of mechanical brake.

4.3.6 Flying start

Flying start enables valid start-up of the motor in case initial speed of a shaft of the drive differs from zero.Five modes of par 1.61 are possible:

0 - function is switched off

1 - search in one direction, search frequency from Fref or Fmax

2 - search in two directions, search frequency from Fref or Fmax

3 - search in one direction, search frequency from Fmax

4 - search in two directions, search frequency from Fmax

Search in one direction should be used for electric drives in which in case of switching off voltage powering the motor, loading will not result in change of a direction of the device.

Search in two directions should be used for electric drives in which in case of switching off voltage powering the motor, loading can result in change of a direction of the device.

In case of modes 1 and 2 search of frequency can begin from the referenced frequency Fref. or from the maximal frequency Fmax. It depends on whether the repeated start begins:

After pressing a key STOP (search from Fref),

After restart of frequ0ency converter (search from Fmax).

For search in one direction it is recommended to set up par 1.61 on 1. In case of search in two directions it is necessary to set up par 1.61 on 2.

4.4 Protection and blocking

4.4.1 Current, frequency and the moment restrictio ns

– Current limit: In order to prevent overloading of the electric drive you can limit maximal permissible output current of the frequency converter – Parameters 1.41 and 1.42 with factory options are set up to value 150 % of nominal current of the drive. System will not allow current to increase higher then this limit.

– Torque limit: In order to exclude mechanical impacts in the electric drive the permissible moment on a drive shaft is

27

Rys. 4.13 Illustration of mechanical brake connection

MFC710

U V WN L230V AC

Kx

set up by means of parameters 1.43 and 1.44. Standard option is 150 % from rating value of the torque.

– Output frequency limit: In order to exclude possibility of setting frequency which considerably exceeds nominal frequency of the drive, parameter 1.40 allows to limit the top limit of output frequency of the converter. Standard option is 50 Hz, and its maximal value – 200 Hz (it is an absolute maximum of output frequency).

4.4.2 Blocking a direction of drive rotation

There is a possibility of partial blocking of the electric drive with permission of operation only in one direction. In this case irrespective of control signals the frequency converter will rotate the drive only in one direction. Parameter 1.65 allows to define this option:

"Reverser" - operation in two directions (option relative)"To the left" - operation in one direction"To the right" - operation in one direction

4.4.3 Blocking the electric drive operation

Switching on one of the arbitrary blocking described below results in drive stopping and makes it impossible to start until the moment of taking down blocking signal (blocking cause). Blocking state is shown on the display (see. fig. 4.15).

External permission and blocking of operation: Two parameters allow to define digital input which will serve as an external signal source for permission and blocking of operation:

par. 2.111 – Blocking of operation – value „Switch off” (default) switches off external blocking of operation. (possible options: Switch off, DI1...DI6 )

par. 2.110 – Permission of operation - value „Switch on” (default) permits operation in spite of state of digital inputs (possible options: Switch on, DI1...DI6 )

Blocking from thermorelay or thermistor in the dri ve: parameter 3.1 permits to switch on thermorelay blocking(see section 4.4.4.2).

External emergency stop: instant stop of the drive in “coast” mode (see par. 2.112 – possible options: Switch off, DI1...DI6). „Switch off” by default – function does not operate.

Blocking from „F STOP”: There is a built-in blockade in referencing-unit structure. It is switched on by parameter 2.14. If it is set on "No" par. 2.13 determines the minimal frequency value, below which frequency will not decrease (by default 0.5 Hz). If par. 2.14 is set up on value "YES" par. 2.13 determines the blocking frequency. If value of frequency decrease under level from parameter 2.13 blockade is activated (STOP). If frequency increases above the restriction set with par. 2.13 will result in repeated start of a drive. The mode of switch on / off will be coordinated due to the characteristic such as “loop of hysteresis” (see fig. 4.16).

4.4.4 Thermal protection of the drive

Par. 2.13

the temperature of windings changes according to exponential law, the drive achieves the maximal temperature for continuous work at a rated current

change of temperature depends on a ratio (I/In) 2, the constant of time of cooling for stopped drive is four times more than a constant of time of heating during

operation

Relative long-term motor current value for frequency higher then 25 Hz is determined by parameter 3.3 . For frequency lower then 25 Hz long-term current is lower (smaller efficiency of the cooling fan which is placed on a drive shaft) and it is determined by parameter 3.4 . These parameters are determined in comparison with rating value of a drive current (for 100.0 % = In). Thus the area of long-term work (fig. 4.17a) is defined.

When cooling the motor without additional ventilation (only with the internal fan) par. 3.4 is necessary to set up on value of 35 % of rated motor current. If additional ventilation of the drive is used value of par. 3.4 can be set up to 75 %. If the motor current is outside of defined area of long-term operation the calculated temperature will increase above 100 %. When the calculated temperature achieves value of 1 05 % electric drive will stop (the message of failure will appear (fig. 4.18)). Such situation is represented on fig. 4.17c for a increase in temperature marked by a dotted line.

Speed of increase in calculated temperature is determined by parameter 3.5 - a constant of time of motor heating. It equals time after which the temperature of the drive will achieve 63 % from value of a final gain. In practice it is possible to accept option:

Par. 3.5 = 120*t6 [min], where t6 [s] is provided by motor manufacterer

Demonstration values of constants of time are resulted in table 4.7.

4.4.4.2 Protection with help of thermorelay fuse or thermistor built-in the drive

With purpose of protection from overheating it is possible to use thermorelay or thermistor built-in the drive. The digital input 6 (DI6) is used for connecting signal to the converter. It is necessary to set up a switch J5 depending on type of the sensor (fig. 2.6 and fig. 4.19).

5. The first start

Before first start of the converter MFC 710 it is n ecessary to check section 4 “Configuration of frequ ency converter”.The structural circuit of control MFC 71 0 and Appendix C – table of parameters of MFC710/A cR are also very important

Main options:

nominal parameters of the drive (see section 4.1)

“control place” A or B

parameter 2.1 “Control B”

“Switch off” = Control A

“DI1” = Choice A/B with help of digital input 1

...

“DI6” = Choice A/B with help of digital input 6

“Switch on” = Control B

Source of signal START/STOP (local from control panel, remote from digital inputs, remote from RS or others):parameter 2.4 “START A” - source of signal START for control Aparameter 2.5 “START B” - source of signal START for control B

method of referencing frequency or rotation speed of the motor (local from control panel, remote from analog input, through link RS, motopotentiometer, from PID-regulator or others):

parameter 2.2 “START A” - source of referencing-unit for control Aparameter 2.3 “START B” - source of referencing-unit for control B

5.1 Vector control mode. Identification run.

In order to operate electric drive in a mode of vector control, except for switching on mode Vector1 (with encoder) or Vector 2 (without the sensor of rotor position) with help of parameter 1.20, it is necessary to enter parameters of an equivalent circuit of the drive (see section 4.1). If these parameters are not known it is possible to use the built-in procedure of parameters identification . After its switching on the frequency converter will made 2 or 3 tests of the drive during which attempt of determination of equivalent circuit parameters will be carried out.

5.1.1 Stages of identification run

Identification of parameters is divided into three stages:

– Stage 1: DC probing. The drive is stopped, the device defines active resistance of stator Rs,– Stage 2: AC probing. The drive is stopped, the device defines active resistance of rotor Rr, inductance of stator

Ls and rotor Lr,– Stage 3: Experiment with rotation at 50 Hz or 25 Hz. The drive rotates powered by voltage with frequency of 50

or 25 Hz - the device defines inductance Lm.

5.1.2 Switching on identification run

!!! CAUTION!!! Before switching on of parameters id entification mode it is necessary to enter nominal parameters of the drive which are described in sect ion 4.1 (nominal power, current, voltage, frequency and speed) - entering erroneous parameters can result i n damage of the motor and the frequency converter .As far as it is possible the motor should be discon nected from loading in stage 3, during which the mo tor accelerates till speed that corresponds to frequenc y of 50 or 25 Hz.

To start procedure of parameters identification it is necessary to set up parameter 1.10 “Identification run” on one of values:

50 Hz run - all 3 stages of identification are carried out, stage 3 at 50 Hz. 25 Hz run - all 3 stages of identification are carried out, stage 3 at 25 Hz. No run. - 3rd stage of parameters identification isn't carried out (in case when there is no possibility to

perform tests with loading and it cannot be disconnected).

After setting parameter 1.10 on one of the options above mentioned the display of the control panel will look as it is shown on fig. 5.1a. After pressing one of keys START (left arrow or right arrow) procedure of parameters identification begins - fig. 5.1b, 5.1c and 5.1d. Depending on parameters of the drive stages 1 and 2 can last from several seconds up to several dozen seconds. The stage 3 lasts about 20 sec. After completing all tests calculated parameters are written to EEPROM memory of the frequency converter (fig. 5.1e). Pressing STOP button will reset and restart converter. It is possible to interrupt procedure of testing in the same way at any moment.

In case of interruption of identification process b y a STOP button before its ending the new parameters of the drive will not be stored.

31

ATTENTION. In case of the third option (No run ) parameter Lm is estimated on the basis of other nominal parameters of the motor. Because of that par. Lm can be erroneous.

ATTENTION. Parameter Rr is estimated on the basis of nominal parameters of the motor. The rated speed of the motor (par 1.2) has the greatest influence on parameter Rr. In case of observing that speed of the motor increases / reduces after its loading it is necessary to accordingly increase / reduce, par 1.2 (it will cause similar reduction / increase of Rr).

ATTENTION. In case of full identification procedure (three stages) which is carried out when encoder is connected, there is no necessity to carry out change in par 1.81 (Enc. Reverser) because the direction of encoder pulses count is simultaneously identified and correction of par 1.81 is carried automatically out.

The error during parameter identification of the drive (fig. 5.2) can occur if: the motor is not connected to the frequency converter, The motor has damages, The current during identification has exceeded 170 % of rated current

of the drive, There is no possibility to define parameters for this drive.

After setting up parameters of the motor and contro l the electric drive is ready to operate.

5.2 Storing and reading of options for 4 different drives

There is an possibility of storing in memory EEPROM four groups of the parameters connected with different motors. It enables to use one frequency converter to operate with four motors. Thus there is no necessity to change option of parameters manually. The structure of parameters set consists of:

• rated motor power (par 1.1),• rated motor speed (par 1.2),• rated motor current (par 1.3),• rated motor voltage (par 1.4),• nominal motor frequency (par 1.5),• nominal motor cosφn (par 1.6),• active resistance of stator (par 1.11),• the main inductance (par 1.13),• inductance of stator (par 1.14),• inductance of rotor (par 1.15),• speed regulator amplification (par 1.70),• constant of integration of speed regulator (par 1.71),• torque regulator amplification (par 1.72),• constant of integration of torque regulator (.1.73),• stream regulator torque (par 1.74),• constant of integration of steam regulator (par 1.75),• quantity of encoder’s pulses (par 1.80);• counter of encoder’s pulses reverser (par 1.81),• current setting of the motor thermal protection (par 3.3),• thermorelay’s setting for stopped motor (par 3.4),• constant of time of motor heating (par 3.5).

STORINGTo store the parameters mentioned above it is necessary to choose number of the memory buffer in par. 1.18 (from 1 up to 4) which will store parameters and to confirm record. The choice of buffer "0" will result in records deleting.

RESTORINGTo restore the parameters which have been recorded earlier it is necessary to choose the memory buffer in par 1.19 (from 1 up to 4) in which parameters have been stored and to confirm reading. Reading empty buffer or buffer "0" will not result in changing current parameters.

ATTENTION. Procedure of record / reading can be made only when the drive is stopped.

6. Failures and warnings

6.1 Messages on failures and warnings on the contro l panel

The luminescence of a red light-emitting diode (LED) and messages (fig. 6.1) signals about failure state.

Thus the frequency converter passes to STOP mode. To make the next START it is necessary to deal with a failure and to erase the message of failure. In case of some failures the automatic restart (deleting of the message) is possible after disappearance of the failure reason. Warning state is signaled by the appropriate message on the display without stopping the frequency converter, and also by a blinking red light-emitting diode LED (fig. 6.2). Warning is automatically erased after a drive stop.

In both cases functioning of a control panel is not blocked. It is possible to look through and change all parameters of the converter without obstructions.

6.2 Deleting failure message. Automatic restarts.

6.2.1 Manual deleting Push for at least 2 seconds

6.2.2 Deleting through a digital input of the conve rter

The parameter 3.70 allows to choose a digital input which will serve for deleting message of failure

6.2.3 Remote deleting through RS link

If parameter 4.7 allows to operate with RS control mode, sequence of 2 next records in the register 2000 (MODBUS) deletes failure message. The detailed description of separate bits and methods of deleting can be found in the description of the register 2000 - section 13.

6.2.4 Readiness to restart if the reason of failur e has not disappeared

If one of the methods mentioned in sections 6.2.1... 6.2.3 deleted the message of failure and the failure reason has not disappeared, the electric drive will be stopped in „ready to restart” state (fig. 6.3).

When the reason of failure will disappear automatic restart of the electric drive will begin.

6.2.5 Automatic restarts

If the electric drive stops after failure there is a possibility of automatic operation restart after reason of system failure disappears. The parameter 3.71 (amount of automatic restarts) restricts allowable quantity of automatic restarts in a time period defined by parameter 3.72. Restart delay from the moment of failure reason disappearance is defined by parameter 3.73 (fig. 6.4).

The electric drive will not restart operation automatically if the internal counter of failure will achieve the value limited by parameter 3.71 in time period determined by parameter 3.72. In this case operation restart will be possible only after deleting failure message by one of methods mentioned in sections 6.2.1... 6.2.3

The permission on automatic restarts is possible after setting value "YES" to parameters: par. 3.74 (for failure Low Udc) par. 3.75 (for failure High Udc) par. 3.76 (for failure High current) par. 3.77 (for failure High temperature of a radiator) par. 3.78 (for failure Failure of an analog input)

6.4 Failure log

Parameters 3.80...3.111 form the Failures Log allows to display a history of last 16 failures.Each record in the failure log consists of two parameters. First informs about failure code (fig. 6.5a), and second - about time of its occurrence (fig. 6.5b). Parameters 3.80 and 3.81 are the newest records of failure, and parameters 3.110 and 3.111 are the oldest records of failure.

35

In a time of one hour of the converter operation the same failure can take place many times. In order to prevent overflow of the failure log, only the quantity of failures which occurred in last operating hour (see fig. 6.5a) is increased. Thanks to this the real quantity of failures which the failure log can remember increases.

7. Sets of factory parameters

The way of loading factory parameters in the converter is shown in section 3.2.7. There are 9 various sets of factory parameters (table 7.1) intended for loading standard, most used control programs.

Frequently in the beginning it is better to load one of the instanced standard sets of parameters, than manually change a lot of parameters of the frequency converter. After loading factory settings it is necessary to change only those options which should be changed to adapt operation of the converter for specific conditions.It is important to remember that after loading any set of factory parameters, it is necessary to defin e factory parameters of the connected motor and in case of us ing vector mode to carry out drive identification ( see section 4.1 and 5.1).

8. PID – regulator

Frequency converter has a PID- regulator (Proportional – Integral - Differential). The regulator can be used for stabilization of any parameters at fixed level (fig. 8.1).

8.1 Turning on and a configuration of the PID-regul ator

To enable PID – regulator as a source of referenced frequency it is necessary to set up par. 2.2 (for control A) or 2.3 (for control B) on value OutPID (fig. 8.2).

8.2 Restriction of saturation and SLEEP function

When the positive or negative error of regulating is kept some time it can result in saturation of the PID-regulator. To prevent this phenomenon, it is necessary to limit output value of the regulator:

• the lowest output value - par. 2.67 (by default 0.0 %)• the highest output value - par. 2.66 (by default 100.0 %)

Function SLEEP of the PID-regulator enables to shut down automatically the drive when output value of the PID-regulator which is simultaneously the reference of frequency is kept on minimum determined by par. 2.67, during a time determined by par. 2.70. The electric drive will be blocked in this case. Unblocking will occur automatically when one from below conditions will be fulfilled:

– the output of a regulator will achieve value higher than value par. 2.67 + par. 2.71– the error will be higher than par. 2.71

Functioning of restriction and SLEEP blocking is shown on fig. 8.4

9. Reeler calculator

MFC710/AcR has built-in application of reeler calculator RC (see fig. 9.1).

For determining current diameter of a roller there is necessary an information about linear speed of rolled medium. In presented example linear speed signal is obtained from frequency converter which cooperates simultaneously in production line.

9.1 Turning on and configuration of RC

To activate RC you should set par 2.9 (for A control) or par 2.10 (for B control) on „Ref.RC” (fig. 9.2).

CAUTION: RC application works only with vector cont rol (par 1.20 „Vector 1” or „Vector 2”).

CAUTION: Instead of configuring all parameters of A pplication separately it is better idea to load factory settings number 9 and then modify only some parameters. This set is especially intended fo r Reeler Calculator Application. Description of loading factory setting s can be found in section 3.2.7.

Table 9.1 – Parameters of reeler calculator

10. Pump Group Controller

The MFC710/AcR built-in control system of pump group (or ventilating fans) enables to control group of maximum 5 pumps (or ventilating fans). Standard frequency converter MFC710/AcR has 4 digital outputs and can serve 4 pumps. The fifth pump can be connected with the help of the optional expansion module. One of controlled pumps is the pump with an adjustable speed of twirl (it is connected to the frequency converter), and other pumps are connected automatically to work from a mains when needed. Working frequency (pressure) and also quantity of working pumps are adjusted in feedback using PID-regulator of the converter or directly from any referencing-unit. One pump works with a rotational speed which is adjusted by frequency converter MFC710/AcR, it is “the leading pump ”. Other pumps are switched on/switched off depending on necessity and powered directly from supply network (these are additional pumps ). The frequency converter decides which of pumps is the leading one and also automatically replaces the leading pump and turns on/shuts down additional pumps.

System with control of group of 3 pumps is shown on fig. 10.1. If the operating mode with pump control is chosen (the parameter 5.10 "Switch on pumps” is set on "YES") to each pump will be allocated one digital output of the frequency converter:

Pump 1 - an output (relay) K1Pump 2 - an output (relay) K2Pump 3 - an output (relay) K3Pump 4 - digital output DO4 (an open collector)Pump 5 – option

To provide safe work of pump group shown on fig. 10.1 it is necessary to mount the circuit of control of pump group as on fig. 10.2. Switches S1, S2 and S3 enable to change a configuration of pump as switched off (0) / switched on directly from a network (R) / controlled automatically by the frequency converter (A).

On fig. 10.2 there is an assumption that inputs that allow/block the pump operation with parameters 5.16, 5.17 and 5.18. are established on control from digital inputs DI1, DI2 and DI3 of the frequency converter (as it is in a set of factory parameters no. 2) and also, that digital outputs of converter K1, K2 i K3 are control signals of turning on pumps (par. 2.90 = „ 76> pump1 ”, par. 2.92 = „ 77> pump2 ”, par 2.94 = „ 78> pump3 ”).

10.1 Parameters of a pump group controller

The description of pumps group controller parameter can be found in Appendix C - see parameters from 5.10 to 5.28 .

ATTENTION: Instead of setting all parameters of the Control system separately, it is better to load a s et of factory parameters number 8. This set is specially intended for a configuration of the Control system of pump group. The description of loading of factory parame ters is in 3.2.7.

After loading this set of factory parameters it is possible to change some of them to adapt work of a control system of pumps for this concrete case.

10.2 Turning on pump group controller

Switching on pump group controller activates after setting up parameter 5.10 on value "YES". Besides the configuration of the parameters 5.11...5.28 is responsible for functioning of a pump group controller and also 2.90, 2.92 and 2.94 assign digital outputs function of switching the pumps on . The parameter 2.2 (or 2.3) is necessary to be set up on value „ 137> OutPID” or „ 161> PumpG.”. For operation with the PID-regulator it is necessary to determine parameters of a regulator - especially a signal source of pressure and the pressure referencing-unit - par. 2.60 and 2.61. In addition parameters restricting a range of regulator’s output - par. 2.66 and 2.67 should be set up on values 100% and 0 % respectively.

Simpler way of setting up parameters is loading of f actory parameters, set number 8 which is especially prepared for a pump group controller group, with su bsequent changing only some options.

10.3 An operating mode with the PID-regulator and a mode of direct control

The pump group controller can operate in two modes::

– standard - when pressure control is adjusted by means of the PID-regulator of the frequency converter (when par. 5.27 = „158> Ref. PID”),

– direct - when the referenced signal decides directly (without PID) about quantity of operating pumps.

In most cases operation in a standard mode, when par 5.27 "Reference-unit choice” is set up on „158> Ref. PID”, is recommended. Any other setting of this parameter will result that the control system will operate in a direct mode - in this case quantity of operating pumps and also speed of twirl of the leading (adjustable) pump will be set up directly by chosen with parameter 5.27 source in limits from 0 to 100 %. For 50 % half of pumps operates, for 0 % one pump operates on the lowest speed, for 100 % all pumps operate.

In a standard mode the quantity of operating pumps and speed of the leading pump is determined by the PID-regulator on the basis of current referenced value (desirable pressure) and also value of current process (current pressure). Signal of referencing-unit's pressure is set up with the help of parameter 2.60 "Ref.PID choice” and the signal of current pressure is set up by parameter 2.61"InPID choice”. It is possible to set up, for example, that the referenced signal from a control panel and a signal of actual pressure from an analog input of the frequency converter. In addition the PID-

regulator can control rotation speed of leading pump if the parameter 2.2 (frequency referencing-unit for control A) is set on value „137> Out.PID”..

In a mode of direct control the parameter 2.2 (frequency referencing-unit for control A) must be set on value „161> PumpG’. This option is outside of standard range of parameter's 2.2 options. In order to make such option of par. 2.2 available, it is necessary to set up par. 4.6 "Full pointers” on value "YES".

10.4 A configuration of pump amount and operating m odes of separate pumps - blocking of pumps

Maximum quantity of pumps which are switched on simultaneously is set up by parameter 5.28. For example, if a group of 4 pumps which are active (can operate under control from pump group controller) but we want only 3 of them to work SIMULTANEOUSLY. For this purpose par. 5.28 should be set on "3".

Parameters 5.16 (for the Pump 1)... to 5.20 (for the Pump 5) define signals activating each pump. Value „ 0> Sw. off means that the pump will be always in inactive mode (the control system will not use it). Value from „ 1> DI1” up to „ 6> DI6” means that this pump will be activated/deactivated with the help of the corresponding digital input of the converter (if the pump is in an active mode and operates and will be deactivated, its immediate shutdown will occur). Value „ 7> Sw.on” means that the pump will be constantly active - there will be no opportunity to block its operation. The pump in an inactive mode cannot be switched on in operation neither as leading nor as additional.

Parameters 5.11 to 5.15 determines operating modes for each pump. There are two opportunities:

– MFC / MAINS– MAINS ONLY

MFC / MAINS - the pump can be the pump with regulated by converter speed of a rotation (the main pump) and also can operate as an additional pump powered directly from the network,MAINS ONLY - the pump can operate only as an additional pump powered directly from the network.

10.5 Monitoring work of pumps

It is possible to monitor state of pump group controller by means of par. 0.34. (fig. 10.3).

The information about state of the Control system of pumps group can be highlighted on the main display of the panel (fig. 10.4) during drive operation.

10.6 Conditions of switching on/off additional pump

The additional pump is switched on under conditions:• output signal of the PID-regulator attains value of 100 %• the level of pressure signal is less than referenced pressure by value of parameter 5.26 (or more)• two previous conditions are carried out through a time which is set up by parameter 5.22

After fulfilling the conditions mentioned above the leading pump reduces a rotational speed up to value determined by parameter 5.25. When the pump achieves this rotational speed, additional pump is switched on. As a result of switching the pressure in system increases. If pressure will stay in range <Selected Pressure +/-par. 5.26> the control system will continue operation without changes. If pressure again reduce - the next additional pump (if it is active - ready to switching on) will be switched on. Otherwise, when pressure will still increase the last additional pump will be switched off.

The additional pump will be switched off under conditions:• the PID-regulator output has reduced up to 0 %• the level of pressure signal is higher than referenced pressure by value of parameter 5.26 (or more)• two previous conditions are carried out through a time determined by value of parameter 5.23

After fulfilling the conditions mentioned above the last additional pump is immediately shut down.

10.6.1 Priority of switching on/off additional pumps

First additional pump that will be switched on, is the pump with number next to the number of the leading pump - according to a sequence shown on fig. 10.6).When the control system makes a decision to switch on the additional pump, the first pump of sequence, which isn't blocked and is not running, is switched on (see fig 10.6a). The first checked pump is the following pump from sequence after the main pump (e.g. when the main pump is P2 the first according to sequence is P3).

When the control system makes a decision to switch off the additional pump, the first pump of sequence (see fig 10.6b), which is currently working, is switched off . The first checked pump is the pump which is located in sequence on the previous position to the main pump (e.g. when the main pump is P2 the first in sequence is P1).

Example 1:If the main pump is 2, switching on sequence of additional pumps is following:

P3 → P4 → P5 → P1switching off sequence: P1 → P5 → P4 → P3Condition: the maximum quantity of pumps is set up on 5, all pumps are not blocked.

Example 2:If pumps P2 P4 are blocked and the main pump is P1 in this case switching on sequence is following:

P3 → P5switching off sequence: P5 → P3

If working pump will be blocked, it will be immediately switched off. Thus, when after certain time if conditions of the switching on the additional pump are satisfied, first ready to operate pump from sequence (see fig. 10.6а) will be switched on. If during operating time the main pump is blocked, all pumps (main and additional) are immediately switched off.When the quantity of operating pumps (including main) is equal to value of parameter P limit (5.28), even if conditions of switching on are fulfilled and there is not blocked pump ready to run – not any more pump will be switched on.

10.7 Automatic replacement of pumps

After time of leading pump operation (determined in hours by parameter 5.2) expires Pump Control switches off the leading pump and replaces it by other accessible pump and starts counting operation time of new leading pump..

Replacement of the leading pump allows to distribute an operating time of each pump in system.

For automatic pump replacement the following conditions must be satisfied: the pump operating at present has worked the quantity of hours determined in parameter 5.21 the tasked pressure is less or is equal to a threshold determined in parameter 5.24 (blocking of replacement at high

loading of network) there is accessible at least one pump (except leading pump) which is not blocked and its configuration allows to

operate as leading pump (MFC/MAINS), parameter P limit (5.28) is set up on value 2 or more

When mentioned above conditions are satisfied the system passes to consecutive replacement of the leading pump. With this purpose: in series of 2-seconds intervals all operating additional pumps are switched off according to sequence at the fig.

10.6b; in two next seconds the leading pump is switched off; through following two seconds the new pump is switched on. It is picked out of unblocked and ready to operate (with

signal from the frequency converter) pumps. It is the next pump in sequence (see fig 10.6a) after last used leading pump;

the system will begin a normal operation and in case of need it will switch on the additional pumps.

REMARKIf the system has been switched off from a supply network, after switching on power the same pump will be switched on as a leading pump, as before. The amount of operating hours before switching off power is remembered and taken into account at the subsequent switching on.

If the main pump is blocked, other pumps are immediately switched off. After that the system will switch on next (according to a sequence from fig. 9.6a) main pump provided that it is not blocked and can operate from the frequency converter.

By momentary blocking of main pump operation you can force replacement (accelerated) of this pump.

11. Advanced programming of MFC710/AcR

In order to use completely the frequency converter possibilities and to seize art of its programming it is necessary to familiarize with some concepts:Characteristic point (abbreviation: PCH) - any from accessible 512 values which characterize current state of the converter’s operation, for example, there are characteristic points which are responsible for a state of digital input and outputs, values of referencing-unit’s signals and also points which are outputs of control unit PLC, etc. (see section 11.1)Pointer - parameter which decides about what among disposable 512 characteristic points (PCH) will be taken as input value in certain place of process (see sections 11.1 and 11.2). Many of the standard parameters determining operation of MFC710/AcR are, in essence, pointers that makes possible, for example, to control the electric drive operation with the help of built - in control system PLC.

11.1 Characteristic Points (PCH)

Each of 512 Characteristic Points is a 16-bit number and can accept a numerical value from range 0 up to 65536 for unsigned numbers, or from -32768 up to 32767 for numbers with a sign. If this PCH is treated as digital value (logic 0 or 1) in this case value “logic 0” corresponds to value PCH = 0, and value “logic 1” corresponds each arbitrary value PCH ≠ 0. PCH are numbered from 0 to 511. Some of them are named in order to display their function on LCD or LED of control panel. Part of PCH remains not used and is intended for future use. In table 10.1 general classification of PCH is presented. The detailed description of every PCH can be found in Appendix A “Characteristic Points”.

Table 10.1 - General classification of PCH

PCH number Value PCH number Value

0...127 Digital variables of process (e.g. Digital inputs) 384...447 PCH, accessible for record by means of RS connection

128...255 Analog variables of process (e.g. Analog inputs)

256...383 PCH, connected with units of internal control PLC

448...511 PCH, connected with optional module of expansions

11.2 PCH and the pointers – how does it work

Pointers and PCH are strictly connected: Value of the pointer (in range 0...511) decides which PCH will be picked - value of this PCH is output value (see fig. 11.1).

11.3 Modification of standard control

Part of parameters in the frequency converter MFC710/AcR are defined as pointers (fig. 11.2). Due to this it is possible to change a standard way of controlling the frequency converter by connecting others PCH by means of these parameters. This РСН can be, for example, outputs of control system PLC which implements any control algorithm. There is an example in fig. 11.2. The parameter 2.2 is the pointer which is set up in PCH no.133 that is the Ref.-unit of Panel (Keyboard). It means: Value of the Referencing-unit A will be taken from the control panel (a). After modification value of the Referencing-unit A can be taken, for example, from an output of unit number 2 of control systems PLC (b).

For security reasons parameters which are pointers and concern operation of the frequency converter have restricted range of selecting PCH. They are reduced to the several standard values. For example for referencing-unit A and B it is possible to choose standard PCH starting from no. 133 to 139 (respectively:referencing-unit of the panel, referencing-unit of analog inputs 0, 1, 2, an output of the PID-regulator, a motor-potentiometer and RS referencing-unit). It secures, that the unexperienced user will not change this parameter to unspecified value. If however the designed application of system demands different from standard setting of the pointer (e.g. in case when for control of the converter it is necessary to use built-in PLC system or a control system of pumps group), in this case parameter 4.6 (“Full pointers”) should be set up on value YES (fig. 11.3).Operation sequence at change of standard control:

1. Unblock possibility of parameters changing (see a way in section 3.2.1),

2. Set Parameter 4.6 on value "YES",3. Change appropriate parameter of the frequency converter (the ),4. If it is necessary block possibility of parameters changing.

11.4 The control panel – defining displayed values

Among parameters from group 0 there are 4 “read only” parameters which can be projected on display in a way defined by a user. Each of these parameters can include value of any PCH. You can define also: measurement unit and quantity of decimal digits. Table 10.2 presents configuration parameters.

11.5 The control panel - definition of user referen cing-units

Directly through Control panel with keys it is possible to change value of referencing-units: of frequency (rotation speeds), of the PID-regulator and also of one of four User Referencing-units (UR1, UR2, UR3 or UR4).The User Referencing-unit can be used, for example, for quick control of process in connection with built-in control system PLC (for example, referencing of quantity of converted pieces of products, selecting time intervals, etc.)There is an access to the User Referencing-unit only when these conditions are satisfied:

current control (A or B) is not set up on frequency referencing (rotation speed) from the Panel (par. 2.2 for control A and par. 2.3 for control B),

the Referencing-unit of the PID-regulator (par. 2.60) it is not set up on the referencing from the Panel,

parameter 4.30 (Choice User Referencing-unit) is set up on value 1 (for UR1), 2 (for UR2), 3 (for UR3) or 4 (for UR4). Value defines choice of active referencing-unit. On fig. 11.5 change of the Referencing-unit for par 4.30 = 1 is shown.

Each of four User Referencing-units (UR1, UR2, UR3 and UR4) has parameters which define: an allowable range of referencing-unit, displayed measurement unit (as in Table 1.5), quantity of decimal places.

The detailed description of parameters about user referencing-unit can be found in the Appendix C - see parameters from 4.30 to 4.51. Parameters 4.32...4.35 enable changes of the referencing-unit even when there is no direct access to it from the Control panel. In order to connect value the User Referencing-unit with structure of control of the frequency converter, four PCH are provided which keep current values of SU1... SU4:

11.6 System of rotation counter

System of rotations counter serves for measuring the amount of rotations of connected to converter encoder. Parameter 4.28 (Scale) determines the quantity of units that correspond to one rotation of encoder. Thus it is possible to scale any quantity connected with performing the rotation. For example, it can be an amount of mm corresponding to one rotation, amount of rotations in appropriate scale..

Counter can be erased by any PCH. Parameter 4.29 (n.rot. reset) defines PCH, which erases the counter. Setting 1 erases and switches off the counter..

Counter counts „up” or „down” in range -32000 ... 32000. Current value of counter is placed in PCH.177.System of rotations counter used in structure of PLC control can serve, for example, to set programmed

quantity of rotations of drive's shaft.

12. PLC controller

In standard variant the frequency converter is equipped with built-in PLC controller which can serve for the control of converter's work or control of any process. PLC controller is switched on when the parameter 5.144 is set up on value YES.

The basic characteristics of control system РLС: 48 universal 3-input units from which each can implement one of 43 logical, arithmetical or time-counting

functions the sequencer unit with a possibility to program a sequence which will consist of maximum 8 states - each

with individually programmed time of operation and a possibility changing state by external signal two 8-input multiplexers which connect to an output one of eight input values depending on control signal 5-point formation unit of curve X→Y which can be used, for example, as the referencing-unit with the

certain characteristic 24 programmed constants accessible also as PCH (can be used as factors in calculations) time of PLC program execution is less or equal to 10ms

Outputs of each PLC units are Characteristic Points, inputs are pointers and that’s why it is possible to connect units among themselves and with parameters of the frequency converter, forming thus structure of a control system.

12.1 Universal functional blocks

There are 48 functional units which don't have precisely limited purpose. Therefore with their help it is possible to implement many control algorithms. Each of these units can perform one of 43 possible logical, arithmetical, time-counting sequencer, multiplexer, curve shaping functions (see appendix B). Each of these units has 3 inputs which have been marked A, B and C and are (depending on the selected function) pointers or constant parameters. Each unit has one output which is a Characteristic Point. OUT of unit 1 has number 256, OUT unit 2 has number 257. and so on, up to OUT of unit 48 which has number 303 (fig. 12.1 and appendix A).Each of 48 Functional units has constantly assigned 4 parameters in 6 group of parameters, for example the Unit 1 has parameters:

Par. 6.1 - function of the unit 1 (see Appendix B) Par. 6.2 - input A of the unit 1 Par. 6.3 - input B of the unit 1 Par. 6.4 - input C of the unit 1

Accordingly, parameters 6.4 up to 6.7 concern the Unit 2, parameters from 6.8 to 6.11 concern the Unit 3 and so on up to the Unit 48.

During PLC operation functions determined by Units are carried out in sequence from 1 up to 48 (always the unit with the lowest number is carried out before the unit with the highest number).

The full operation time of PLC sequence depends on amount of blocks used in program, determined by par. 5.145. This time is equal to T = par. 5.145 x 0.2ms . By default, parameter is set to 50 what limits time of execution to 10ms.CAUTION!!! Units with numbers higher than par. 5.14 5 are not executed!

12.2 Sequencer device

The sequencer (fig 11.2) allows programming up to 8 cyclically repeating operation modes of the converter with the determined times of duration of separate modes. Inputs marked out by arrows are pointers - they take the data from PCH determined by the specified parameter. Input LEN is an ordinary parameter.

In case of defining sequencer as functional unit corresponding inputs A, B and C aren't active. To output of sequencer (which is appropriate PCH of such unit) number of sequence is passed. Number of sequence can be also found in PCH 312.

NEXT Force switching into following state (forward). The input operates at down-up transition of a signal.

PREV Force switching into previous state (backward). The input operates at down-up transition of a signal..

CLR Force transition into STATE 1 when CLR = H (differs from 0).

SET Force transition into a STATE determined by input SETVAL when SET = H (the priority is lower, than CLR).

SETVAL STATE to which the frequency converter passes after supply of signal SET (a range 0...7, there are only 3 youngest bits).

MODE 1...MODE 8

Outputs which correspond to current state of a sequencer. At the same time only one of outputs STAT1... STAT8 have value other than zero.

NR SEQ An output - value 0...7. Number of a current state minus 1.

12.3 Multiplexers MUX1 and MUX2

These are two units which implement the selecting function “1 from 8”. Depending on the input state of SELECT (values 0...7, only 3 youngest bits are important) on the output of the multiplexer (PCH number 313 or 314) value from an appropriate input (from In0 up to In7) is transferred. It is possible to switch off the multiplexer (input Sw.on) then input value of DVAL input is transferred to the output. Parameter PRIOR can adopt a value from 1 (the most high priority) up to 48 (see the description of a sequencer operation - section 11.2).

As in sequencer most parameters (inputs) are pointers. They are presented in fig. 12.4.

12.4 Curve shaping unit

PLC controller contain Curve Shaping Unit (CSU) which can serve, for example, for formation of the characteristic of the speed referencing - changing the characteristic from linear to determined broken curve. CSU is the functional converter of any input value X into output value Y, which depends on the form of a curve which is defined with help of 5 points (X, Y) (see fig. 12.5). These points are determined as parameters of CSU. Input value X is chosen by parameter 5.101. Output value Y is in PCH.315.

CAUTION: conditions X1 ≤ X2 ≤ X3 ≤ X4 ≤ X5 should be satisfied.

12.5 Constants

In cases, when we want to determine a constant value as an input of any PLC block, we can use one of 24 constant values accessible as PCH with number from 320 to 343. These values can be set in range from -32000 to 32000 by means of parameters 5.120 do 5.143..

Example when there is a necessity to use a constant.

It is necessary to execute operation Y = 5 * X where X is an input value and Y is output value. Using universal units PLC, we can execute operation (A * B / C) This is function number 2 (see. Appendix B). We assume A = X, B = 5 and also C = 1, in result we have function Y (an output of the universal unit) = X * 5 / 1

How shall we do it?With parameter 5.120 we set value of Constant 1 to 5,

– parameter 5.120 sets up value of the Constant number 1 on 5.– parameter 5.121 sets up value of the Constant number 2 on 1.– parameter 6.1 (function of the unit 1) is set up on value 2 (function 2, that is A * B / C) – parameter 6.2 (input A of the unit 1) is set up on a signal source X, for example, the analog input 0 = PCH.134) – parameter 6.3 (input B of the unit 1) is set up on the Constant number 1 = PCH.320– parameter 6.4 (input C of the unit 1) is set up on the Constant number 2 = PCH.321

In this connection inputs B and C of functions 2 are pointers, instead of parameters, so they cannot be assigned a constant values. It is necessary to choose the Constant number 1 (PCH.320) from among characteristic points for input B and the Constant number 2 (PCH.321) for input C.The parameter 5.144 “Switching on PLC” is set up on YES.Since this moment PCH.256 (the output of the unit number 1) is the value corresponding to result of operation X * 5, that in our case corresponds to value of an analog input 0 increased 5 times, which means it changes in limits from 0 to 5000 (0.0...500.0 %) (fig. 12.6).

12.6 Example of PLC use

An example presented in this section describes how to control such quantities as output speed and time of drive acceleration by means of built-in PLC.TASK: To modify the process of drive start-up in such way, that the speed characteristics of a drive would look just like it is shown on fig. 12.7.

On fig. 12.7 it is possible to distinct three zones: the First zone - slow acceleration - (Dynamics 1), II zone - the established speed, and also III zone – fast acceleration (Dynamics 2).Frequency converter MFC710/AcR allows to set up 2 different rates of acceleration and braking: Dynamics 1 and Dynamics 2. These rates are determined by parameters 1.30, 1.31, 1.32, 1.33. Parameter 1.36 decides which dynamic is currently active. The parameter 1.36 is a pointer and consequently it can be set up so that one of PLC units decides about dynamics.On fig. 11.7 it is shown, that after the electric drive acceleration (with dynamics1) to speed N1 it is necessary to make time limit T and then to accelerate the electric drive (with dynamics 2) to speed N2. It is necessary to modify parameter 2.2 (Referencing-unit A) so that one of PLC units define an relative level of speed up to which the electric drive should be accelerated (this level corresponds to the nominal frequency of the drive).

On fig. 12.8 the structure which implements a given task it presented. The unit 1 is the comparator which reacts to the value of first speed. In the observed case acceleration with dynamics 1 is implemented to speed of 20.0 % (ST1) of nominal speed. The signal which informs about achievement of the first value of speed enables Unit 3. The Unit 3 is the counter which counts downwards from value 5 (ST3) every 1 second (constant speed for 5s). The output signal of the Unit 3 enables the Unit 4 and switches type of dynamics (Dynamics 1 or Dynamics 2). The unit 4 is a switch which, depending on a signal on input, passes to the referencing-unit A the first or second value of speed (ST1/ST2). Value of balance time (ST3), first (ST1) and second (ST2) speed can be modified by connecting in proper place, for example, an analog input or one of user referencing-units. Condition: ST2> ST1 must be fulfilled.

To realize such structure it is necessary to:1. define the Unit 1 (par. 6.1 = 12, par. 6.2 = PCH.176, par. 6.3 = PCH.320, par. 6.4 = 0),2. define the Unit 2 (par. 6.5 = 23, par. 6.6 = PCH.256),3. define the Unit 3 (par. 6.9 = 27, par. 6.10 = PCH.91, par. 6.11 = PCH.257, par. 6.12 = PCH.322),4. define the Unit 4 (par. 6.13 = 9, par. 6.14 = PCH.321, par. 6.15 = PCH.320, par. 6.16 = PCH.256),5. define the Unit 5 (par. 6.17 = 23, par. 6.18 = PCH.258),6. set up parameter 2.2 (Referencing-unit, A) on PCH.259 as it described in section 3.2.1, 3.2.8,7. set up parameter 1.36 (Choice of dynamics) on PCH.260,8. switch on PLC setting up parameter 5.144 on YES.

In above mentioned example the parameter 5.120 will define a threshold of speed N1 [resolution 0.1 %, that is 1000 = 100.0 %], the parameter 5.121 will define a threshold of speed N2 [resolution 0.1 %, that is 1000 = 100.0 %], a parameter 5.122 time T with resolution of one second.

13. Control of the frequency converter by means of connection RS

Frequency converter MFC710/AcR is equipped with RS232 communication link and/or RS485 (depending on variant). It enables to control work of device with help of a computer or an external controller. The basic characteristics and possibilities of the RS link of the frequency converter:

operation with speed 1200, 2400, 9600 or 19200 bits per second, a format of a character: 8 data bits, lack of parity control, 2 stop bits, transfer protocol: MODBUS mode RTU, check of transfer validity with use of CRC sum, unit number (converter) set up with help of parameter (typically 12), support of MODBUS commands: command 3 - “read the register” - allows to read individual registers

from the converter or block of up to 127 registers. command 6 - “register write” - write to individual register in the converter,

possibility of reading of an operating mode, control start/stop, reading and writing of referencing-units, possibility of reading and writing of all parameters of the converter just as by means of a control panel, possibility of reading all 512 PCH and writing 64 of them, which are intended for writing through RS

connection.All operations are based on two basic commands of MODBUS RTU protocol - 3 and 6 which are described in publications concerning МODBUS.

13.1 Parameters which concern communication through RS

Table 13.1 - Parameters which refer to communication

Parameter Description

2.2 Referencing-unit A - it is possible to set up a source "RS"

2.3 Referencing-unit B - it is possible to set up a source "RS"

2.4 Start A - it is possible to set up a source "RS"

2.5 Start B - it is possible to set up a source "RS"

4.7

RS permission – it is possible to enable permanent permission to control from RS, disable permanent permission or, for example, set enabling/disabling RS permission from a digital input. The permission concerns referencing frequency through RS, RS PID referencing-unit, and a START / STOP/BLOCKING signal from RS (see table 13.2 - registers 2000, 2001 and 2002).

4.8 RS speed - possible options is 1200, 2400, 9600 or 19200 bits per second.

4.9 Number of device (converter) in MODBUS protocol (possibility of connecting several converters through one communication channel RS 485).

CAUTION: If control RS blocked (par. 4.7), and parameters 2.2, 2.3, 2.4 or 2.5 define control as "RS" in this case the frequency converter remains in STOP mode or the referencing-unit of frequency will assume value 0.

If, for example, the referencing-units A is set up on value "RS" , to set frequency with RS, there is no necessity to set up bit 5. Forcing of control with RS by means of bits 4,5,6 results in switching off a source of the control established with parameters.Bits 12,13,14 block operation of the drive irrespective of the established type of control (also when, for example, there is control through RS and bits 15 = 1).

13.3 Handling of connection errors

If connection errors appear or if the command with Improper parameter is sent, response of the device is described by MODBUS standard. Possible return error codes are:

1 = unknown command - when the command other than 3 or 6 is sent,2 = wrong address - the address of the register is not supported by the electric drive (there is no such register),3 = wrong value - command 6 tried to send value which is out of range of specified register

In case of wrong transfer (e.g. CRC error) device does not send answers to commands.

14. Information from the manufacturer

Help from PWC "TWERD”The Manufacturer provides the full help during guarantee and postguarantee service, updates of software and

equipment.

Periodic service In case of installation and use of the converter according to its specification, there is no necessity of its frequent

periodic service. It is necessary to pay attention to cleanliness of a radiator and the fan.

Radiator A plenty of a dirt which covers a radiator at operation worsens removing heat from device and can trigger protection against an overheat of the converter. Cleaning of a radiator can be made by means of pure and dry air under pressure using in addition a vacuum cleaner for gathering a dirt.

Fan In case of strengthening noise at fan operation and reduction of its productivity, it is necessary to replace the fan. To replace the fan it is necessary to disconnect a cable feeding the fan, and to unscrew the fan. New fan should be ordered in TWERD.

Resistance PN-EN 61800-3/A11 first and second environment

The first environment: includes the equipment plugged in a low-voltage supply network which powers apartment buildings. The second environment: includes the equipment plugged in a supply network which doesn't power living quarters. Limited distribution: type of distribution at which the manufacturer limits delivery of the equipment to suppliers, clients or users who separately or together have the competence in the field of including electromagnetic compatibility at use of frequency converters MFC710/AcR.Distribution unlimited: type of distribution at which delivery does not depend on the technical competence of the client or the user in the field of requirements which concern to electromagnetic compatibility at use of converters MFC710/AcR.

The frequency converter set up in the first environment without external supply network filter RFI does not exceed value of emission which is admissible for the limited distribution. However there are exceeded limits of value of admissible emission for unlimited distribution. That’s why:

The product belongs to a class with the limited dis tribution which is certain in norm IEC 61800-3.

In the housing environment this product can cause r adio-interferences and in this case user has to accept a dditional

preventing measures.

By analogy in the second environment in which for realization of requirements of emission according to unlimited distribution is not obligatory to use filter RFI, but it is necessary to consider an possibility of radio-interference occurrence.

In IT networks usage of asymmetric filters of high frequency (condensers Y and CY) to reduce emission of interference, ruins the concept of the distributive network isolated from the ground. Additional grounded impedances can become threat of safety in such systems.

For technical reasons in some applicatons (current higher than 400A) fulfilling requirements of EMC is not possible. In such cases user and manufacturer should decide on ways of satisfying EMC requierments in this particular application.

Appendix B - Table of Functions of Universal Blocks

Each Universal Block has 3 inputs which have been marked out A, B and C. These inputs can be pointers or parameters. In the table below following convention of type denoting is used: A (big letter A) means that input A is parameter (value is assigned directly to it), but a (the small letter a) means that the input a is a pointer (it points PCH which contains input value). Inputs B and C are marked in the same way.

Caution: In OUT which is interpreted as logic value (0/1 or not/yes) abbreviation H is used for definition of any value different from zero (logic 1). For definition of «logic 0» value character L is used.
